It's not just in the market chain. It's also in the work area where one works.
I had a real nice coat stolen from the work place coat rack. Then I caught a woman wearing my light cpo coat that she had taken off the coat rack without permission. It was just pure luck that I caught her. There after I locked my coat to the coat rack with a bicycle chain lock. Other employees laughed at me until those that laughed had theirs stolen as well.
I think in all, about six or seven real good coats where stolen in about as many weeks.
The work place didn't do anything about the thefts, the lockers were too small to put a coat in and you had to leave your coat on the coat rack as they weren't allowed in the work area.
Buy a garment lock. They've been standard for furs for years...
